The system of equations will have a unique solution.

A finite set of equations for which we searched for common solutions is referred to as a system of equations, also known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized.

Given that the equations are:-

y=-2x+2 and 2y+4x=4

Convert the equations into general form,

2x + y = 2

4x + 2y = 4

If the ratio of a₁ / a₂ is not equal to the ratio of b₁ / b₂ the equation will have a unique solution. And if are equal than the equation will have infinitely many solutions.

2 / 4 = 1 / 2 = 2 /4

1 /2 = 1/ 2 = 1/ 2

The equation will have many solutions.

Answer: Let's call Sarah's original amount of money as x. Then, Christine had 0.8x.

After they spent $684 altogether, Christine had 0.8x - 0.25(0.8x) = 0.8x - 0.2x = 0.6x left.

Sarah had x - 684.

Since Christine had thrice as much money left as Sarah, we can write an equation:

0.6x = 3(x - 684)

Expanding the right side of the equation:

0.6x = 3x - 2052

Solving for x:

2.6x = 2052

x = 787.69

So Sarah originally had 787.69 dollars and spent 787.69 - 684 = 103.69 dollars.

The number of multiplications for the power₁ is 3 multiplication power₂ is one multiplication and power₃ is 5 multiplications and the number of recursive calls will power2 and power3 make when computing 332 and  319 is 5.

First, let's look at power₁. This function can compute the power of a number by repeated multiplication. For example, to compute 3 to the 4th power, power₁ would perform three multiplications: 3 x 3 x 3 x 3 = 81.

Using this approach, we can see that to compute 3 to the 32nd power, power₁ would perform 31 multiplications (3 x 3 x 3... repeated 31 times). Similarly, to compute 3 to the 19th power, power₁ would perform 18 multiplications.

Next, let's consider power₂. This function uses a different strategy for computing powers. It relies on the fact that any number can be expressed as a power of 2

To compute 3 to the 32nd power using power₂, we would first express 32 as a sum of powers of 2:

=> 32 = 2⁵ + 2⁴ + 2³.

Then, we would use the fact that 3 raised to a power of 2 can be computed with just one multiplication: 3² = 9.

Using this fact repeatedly, we can compute 3 to the 32nd power with only 5 multiplications:

=> 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3.

For 3 to the 19th power, power2 would express 19 as 2⁴ + 2¹ and then use 4 multiplications:

=> 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3.

Finally, let's look at power3. This function is similar to power2 but uses a more efficient algorithm called exponentiation by squaring. This algorithm works by repeatedly squaring the base and halving the exponent until the exponent is 1.

To compute 3 to the 32nd power using power₃, we would start with the binary representation of 32 (100000 in binary).

we can see that power₃ will only perform 5 multiplications to compute 3 to the 32nd power.

Similarly, to compute 3 to the 19th power, power₃ would start with the binary representation of 19 (10011 in binary) and use the exponentiation by squaring algorithm to perform only 6 multiplications.

If the gross income per month is $4000 , then the monthly disposable income will be $2920   .

To find the monthly disposable income, we subtract the various taxes from the gross income.

The Federal tax is = 10% of $4000 = $400  ;

The State tax is = 7% of $4000 = $280  ;

The City tax is = 3% of $4000 = $120  ;

and the Social security tax is = 7% of $4000 = $280  ;

So , the Total monthly tax is = $400 + $280 + $120 + $280 = $1080  ;

We know that the Monthly disposable income = Gross income - Total tax ;

⇒ Monthly disposable income = $4000 - $1080  ;

⇒ Monthly disposable income = $2920  .

The values of a and b in the exponential function f(x) = [tex]ab^x[/tex] can be found by using the two given points and solving a system of two equation.

To find the values of a and b in the exponential function f(x) = [tex]ab^x[/tex] given that it passes through the points (0, 11) and (3, 1375), we can use the supplied positions where a and b must be solved.

Let's start with the point (0, 11). Plugging x = 0 and y = 11 into the equation, we have:

11 = [tex]a * b^0[/tex]

Since [tex]b^0[/tex] = 1 for any value of b, we have:

11 = a * 1

So a = 11.

Next, let's use the point (3, 1375) to find b. Plugging x = 3 and y = 1375 into the equation, we have:

1375 = [tex]11 * b^3[/tex]

Dividing both sides of the equation by 11, we have:

125 = [tex]b^3[/tex]

By combining the cube roots of the two sides, we obtain:

b = 5

So the values of a and b are a = 11 and b = 5. The exponential function that passes through the points (0, 11) and (3, 1375) is f(x) = [tex]11 * 5^x[/tex].

The slope-intercept form of a line is y=2/3x + 2, the line is perpendicular and shifted down 8 is y = -3/2x - 6.

The slope-intercept form of a line is y = mx + b, where m is the slope of the line and b is the y-intercept. In the given equation, y = 2/3x + 2, the slope is 2/3 and the y-intercept is 2.

To find a line that is perpendicular to this line, we need to find a line that has a slope that is the negative reciprocal of the slope of the given line. The negative reciprocal of 2/3 is -3/2, so the slope of the new line will be -3/2.

Now we need to find the equation of the new line in slope-intercept form. We know the slope of the line (-3/2), so we can substitute this value for m in the slope-intercept form and get:

y = -3/2x + b

To find the value of b, which is the y-intercept of the new line, we need to use the fact that the line is shifted down 8 units. We can do this by subtracting 8 from the y-intercept of the given line (which is 2), to get:

b = 2 - 8 = -6

So the equation of the line that is perpendicular to y = 2/3x + 2 and shifted down 8 units is:

y = -3/2x - 6

This line has a slope of -3/2, which is the negative reciprocal of the slope of the given line, and a y-intercept of -6, which is 8 units lower than the y-intercept of the given line.

The power in a significance test is the probability of detecting a true effect, while the probability of making a type II error is the complementary probability of power.

A significance test is a statistical method used to determine whether an observed difference or effect is statistically significant or simply due to chance.

Power is defined as the probability of detecting an effect in a significance test if an effect truly exists. In other words, it is the probability of correctly rejecting the null hypothesis (H0) when the alternative hypothesis (Ha) is true. The null hypothesis assumes that there is no significant difference between two groups, while the alternative hypothesis states that there is a significant difference.

Mathematically, power is calculated using the following formula:

Power = 1 - β

Where β is the probability of making a type II error, which is the probability of failing to reject the null hypothesis when the alternative hypothesis is true. In other words, it is the probability of not detecting an effect when an effect truly exists.

Therefore, power and β are complementary probabilities. If power is high, β is low, and vice versa. A significance test with a low power has a higher chance of making a type II error, meaning that it can fail to detect a real effect. Conversely, a test with a high power has a lower chance of making a type II error, meaning that it can detect a real effect more accurately.

(-3x^5)^2 = (-3x^5) × (-3x^5)

Next, let's multiply this by 4x^3:

(-3x^5)^2 × 4x^3 = (-3x^5) × (-3x^5) × 4x^3

Now, let's multiply the coefficients and combine the exponents:
